| 20110270432 | SCALABLE MANUFACTURING ASSEMBLY VERIFICATION SYSTEM - A scalable manufacturing assembly verification system for use in a manufacturing facility to verify assembly of a product, the system comprising assembly process work stations and assembly verification system stations. The assembly process work stations are each configured to provide at least one device configured to aid in assembly of the product. The assembly verification system stations are each located within a different one of the assembly process work stations, with each of the assembly verification system stations including a computing device in communication with the device, and with each computing device including a respective set of business rules corresponding to the assembly process work station within which the computing device is located, wherein each set of the business rules provides assembly verification for the device to error check assembly of the product with the device. | 11-03-2011 |
| 20110184611 | MULTI-STAGE NON-SEQUENTIAL DOWNSHIFT CONTROL FOR AN AUTOMATIC TRANSMISSION - An improved downshift control for an automatic transmission optimized for sequential shifting achieves a non-sequential fifth gear to third gear downshift by reducing the main pressure of the transmission hydraulic control system, allowing a offgoing clutch to slip, disengaging the offgoing clutch, using torque reduction to control engine speed, engaging the oncoming clutch, increasing the main pressure of the transmission hydraulic control system and using torque reduction to synchronize the transmission input speed with the third gear transmission output speed. | 07-28-2011 |
| 20100179723 | DRIVER BEHAVIOR BASED REMOTE VEHICLE MIS-USAGE WARNING AND SELF-MAINTENANCE - Information associated with vehicle components and sub-systems is monitored by an on-board module, and associated data, either processed or raw, is telematically transmitted to a remote data center by wireless communications. The remote data center archives the received data in a database for each separate vehicle that is part of the system. The remote data center analyzes the data to ascertain whether the data indicates a usage pattern and/or vehicle condition that may have a detrimental effect on certain vehicle components, sub-systems and systems, such as excessive component wear. For example, the data center runs pattern detection algorithms on the data to identify known usage patterns that may potentially impact normal vehicle operation. If such a usage pattern is detected, the remote data center may issue a warning to the vehicle operator, or other designated person, that such usage may have a detrimental effect on the vehicle or vehicle components. | 07-15-2010 |
| 20100033372 | IN-VEHICLE ALERT OF CLOUD POINT IN ENGINE DIESEL FUEL - The disclosure relates to a method for receiving in-vehicle information regarding diesel fuel cloud point condition. The method includes establishing communication between a telematics unit in a vehicle and i) a global positioning system device, ii) a call center including a database, and iii) a cloud point monitoring device in the vehicle. The telematics unit receives from at least one of i, ii, or iii, information pertaining to vehicle location, cloud point, and ambient temperature. The telematics unit determines from the information whether fuel in a fuel system of the vehicle is reaching cloud point or can reach cloud point within a given time period. The telematics unit then transmits an in-vehicle alert when the fuel in the vehicle fuel system is reaching cloud point or can reach cloud point within a given time period. The disclosure also relates to a system for performing the method. | 02-11-2010 |
| 20090148726 | Gas Diffusion Layer for Fuel Cell - A gas diffusion layer for a fuel cell is described. The gas diffusion layer includes a carbon fiber mat having a substantially open structure. Bloomed fibrillated acrylic pulp is added into a microporous layer ink. Alternatively, the bloomed fibrillated acrylic pulp can first be disposed on the carbon fiber mat, with the microporous layer ink added thereafter. When the microporous layer ink/bloomed fibrillated acrylic pulp mixture is coated on the carbon fiber mat, the ink penetrates through the open substrate, and is locked into place by the bloomed acrylic pulp fibers. This allows for a buildup of microporous layer ink on top of the substrate for added thickness when the bloomed fibrillated acrylic pulp sits on top of the mat. | 06-11-2009 |
